The energy transition has far-stretching implications for chemical companies. The Delft e-Refinery institute brings researchers and industrial partners together in order to develop the required technologies and human capital. Researchers in the e-Refinery initiative focus their research on the electrochemical conversion of sustainable electricity, water and air into fuels and chemical building blocks, from the molecular scale to large-scale system integration. Implementing e-Refinery will serve three important challenges that the society is facing: CO2 neutral fuels, seasonal energy storage and a defossilized chemical industry.
Abstract: To meet the demand for more sustainable energy more and more wind turbines and solar panels are being built and put into place. When the sun is shining bright and there is a strong wind these systems produce a lot of electricity and at night or moments with less wind these systems produce less to no energy. The challenge of this type of electricity generation is therefore that it is not constantly available and that the electricity has to be used immediately. It is desirable to find means to store this electricity to match usage throughout the year. The research is developing a unique system in which sustainable electricity can be stored for both the short- (day and night) and long-term (weekly & seasonal) usage.
The novel system consists of a Ni/Fe battery which can store renewable energy for the short term use, integrated with an alkaline electrolyser. The unique feature of this battery system is that when the battery is fully charged the integrated system starts splitting water molecules into H2 and O2 via electrolysis. The H2 can be stored and used for electricity production on the longer terms.
Advanced tests of the system even have shown that the integrated system performs better overall than the individual battery and electrolysis functions separately. The materials used, its efficiency and robustness, and the fact that two applications are combined render the battolyser competitive with other electricity storage applications.

Large-Scale Energy Storage
Substantial implementation of fluctuating energy sources like solar and wind energy requires facilities for long-term, large-scale storage of power. The Large Scale Energy Storage section aims to contribute to solving this problem by targeting its research and educational activities in three directions that can enable energy storage. The first is the electrocatalytic conversion of water, CO 2and N 2 with renewable electricity into bulk chemicals that preferentially fit in our existing energy infrastructure; substituting natural gas and fossil fuel based liquid fuels with high energy
densities. In this line of research the coupling with CO 2 produced by biomass gasification is foreseen. The second line of research concerns the further electrification of the process industry, by coupling hydrogen produced via electrolysis with conventional chemical processes such as the Sabatier reaction. The third line of research is directed towards energy storage via the coupling of biomass/waste with renewable energy sources based on the creation of a synthesis gas platform realized by smart integration of novel biomass/waste gasifiers.
The Energy Technology Section is part of the Process and Energy Department of the Mechanical, Maritime and Materials Engineering (3mE) faculty at the Delft University of Technology. Research and education focus on the design and modeling of thermal energy conversion systems, with a focus on renewable energy. Our lively group consists of around 35 scientific staff members (professors, research associates and PhD students) and, at any time, approximately 40 M.Sc. students. We also manage excellent research facilities. The group has a long history that
dates back to the 1960's.

Energy Snack: Senior Technology Manager TU Delft and Executive Board Member of e-Refinery. We can facilitate building new sustainable industries by bringing together scientists, engineers, equipment developers, manufacturing industries and regional and (inter)national authorities. That is what we do at e-Refinery; we co-develop it!
Prof.dr.ir. W. de Jong
Rather than CO2 being a waste product, it is much more interesting to think of it as a reusable, and thereby sustainable, raw material.
Prof. Fokko Mulder
The focus of his research is the fundamentals as well as practical aspects of energy storage and conversion materials for renewable energy applications.
Dr Ruud Kortlever (assistent professor)
His group is interested in electrochemical conversions that are relevant for renewable fuel production and the electrification of the chemical industry. With the help of mechanistical insights, modelling and theory predictions his group contributes to solving contemporary energy problems by developing new electrocatalytic systems and devices.
